02/22/2023, 12:21 AMHello all,
I am new to efabless, but I have some experience with ASIC designs, I taped out more than a handful of analog mixed signals designs in various technologies.
I am new to setting up an environment using github, python and docker.
I ran into a setup issue and I would appreciate some help.
These are the steps and the issue I ran into:
0. I use a ubuntu 20.04.5 LTS installed under an Oracle VirtualBox on a Windows 11 operating system.
Python command runs as python3
1. I created a new repository based on the caravel_user_project
2. I followed the steps until <make setup> command and verified they ran without errors. the environment variables were set properly
3. I ran the setup command and got some warnings regarding Docker,
4. There are errors regarding permission denied to access Docker daemon
Could you hint me as what I am not setting up properly?
Below is an excerpt of the terminal window messages:

02/22/2023, 12:26 AMHello and welcome! Are you targeting sky130 or gf180? How much RAM did you allocate to the virtual machine in VirtualBox?
Philipp Gühring
02/22/2023, 12:35 AMI think DOCKER_SWAP and DOCKER_MEMORY are not needed (at least I didn't need them yet). With ROUTING_CORES you could define how many parallel CPU cores should be used for routing (you might want to increase it if you still have enough RAM left and the processor utilisation isn't too high).
Philipp Gühring
02/22/2023, 12:36 AMBut the STD_CELL_LIBRARY is an interesting option which I would suggest to set now, there you can define which standard cell library should be used.
Philipp Gühring
02/22/2023, 12:37 AMRegarding the permission errors, I would suggest to try it as root (by using "su" or "sudo"), or you could try to add your username to the "docker" group in /etc/group

02/22/2023, 1:24 AMThanks, will ty to add myself to docker group. sudo or su root did not work.
As for RAM, standard cells, etc... I just want to get a feel how the tools work: openlane, magic, layout and simulators first, then will try to submit something
Dorin Emil Calbaza
02/22/2023, 3:11 AMI added myself as user in the docker group, deleted the folder and started from git. I get the same warning and errors. I could not find the command that calls the docker daemon.

Philipp Gühring
02/22/2023, 7:49 AMHave you installed docker already?
d
Dorin Emil Calbaza
02/22/2023, 1:10 PMYes, I found out that I needed to add myself to the docker group
My issues came from a fresh installation of UBUNTU. It has python, but also needs pip.
I list below the commands that add docker and pip in ubuntu, as well as what is needed to make them work properly. After that I was able to run make setup without issues.:
**************************************************
Copy code
# Commands to install docker and python pip module in Ubuntu. They are needed!
# docker, install and adding user_name to docker group
sudo apt-get remove docker docker-engine <http://docker.io|docker.io> containerd runc
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli <http://containerd.io|containerd.io> docker-buildx-plugin docker-compose-plugin
sudo usermod -aG docker <user_name>
sudo docker run hello-world
# install pip
sudo apt update
sudo apt install python3-pip
sudo usermod -aG docker dorin
python3 -m pip --version
# good time to reset your ubuntu👍 1
